Question 1
The primary purpose of structural engineering is to:
A. Design decorative finishes
B. Ensure structures safely resist applied loads
C. Select construction colors
D. Manage accounting records
Correct Answer: B. Ensure structures safely resist applied loads
Rationale: Structural engineers design systems that safely support loads and
maintain stability.
Question 2
A dead load is:
A. A permanent load from the structure itself
B. A temporary moving load
C. A wind pressure load only
D. An earthquake load only
Correct Answer: A. A permanent load from the structure itself
,Rationale: Dead loads include the weight of structural components and
permanently attached materials.
Question 3
A live load is:
A. A permanent foundation load
B. A variable load caused by occupants or movable items
C. The weight of concrete only
D. A thermal load only
Correct Answer: B. A variable load caused by occupants or movable items
Rationale: Live loads change over time and commonly include people, furniture,
and stored materials.
Question 4
Wind load primarily produces:
A. Lateral forces on structures
B. Only vertical compression
C. Permanent material weight
D. Concrete curing effects
Correct Answer: A. Lateral forces on structures
Rationale: Wind applies horizontal pressures that must be resisted by structural
systems.
Question 5
Seismic loads are caused by:
A. Ground motion from earthquakes
B. Rainfall accumulation
,C. Material expansion only
D. Gravity loads
Correct Answer: A. Ground motion from earthquakes
Rationale: Earthquake forces result from the acceleration of the ground and
structure.
Question 6
The SI unit of force is:
A. Meter
B. Newton
C. Pascal
D. Joule
Correct Answer: B. Newton
Rationale: The Newton is the SI unit used to measure force.
Question 7
Stress is defined as:
A. Force divided by area
B. Area divided by force
C. Force multiplied by length
D. Length divided by area
Correct Answer: A. Force divided by area
Rationale: Stress represents the internal force intensity within a material.
Question 8
Strain is defined as:
, A. Change in length divided by original length
B. Force divided by area
C. Weight divided by volume
D. Moment divided by force
Correct Answer: A. Change in length divided by original length
Rationale: Strain measures deformation relative to original dimensions.
Question 9
Young’s modulus represents:
A. Material stiffness
B. Material density
C. Material weight
D. Material color
Correct Answer: A. Material stiffness
Rationale: Young’s modulus relates stress to strain in elastic materials.
Question 10
Elastic deformation occurs when:
A. A material returns to its original shape after unloading
B. A material permanently changes shape
C. A structure collapses
D. A material melts
Correct Answer: A. A material returns to its original shape after unloading
Rationale: Elastic deformation is reversible.
Question 11
Yield strength is the stress level where a material:
